A dictionary attack in cybersecurity is a type of brute-force attack used in cybersecurity to crack passwords. In this method, attackers systematically try every word in a predefined list, or “dictionary,” to guess a password. This list often includes common words, phrases, and number combinations that people frequently use as passwords, such as “password123” or “qwerty”.
How It Works:
1. Preparation: The attacker compiles a list of potential passwords, often using common words, phrases, and variations.
2. Execution: Automated tools run through this list, attempting each word as a password.
3. Outcome: If a match is found, the attacker gains access to the account.
Prevention Tips:
• Use complex passwords: Combine upper and lower case letters, numbers, and special characters.
• Avoid common words: Don’t use easily guessable words or phrases.
• Regularly update passwords: Change your passwords periodically to reduce the risk.
